  1. We have encountered the same reading problems problem with the WD5000YS in a raid 5 configuration. They perform well in Raid 0,1 though, and as a normal drive. WD5000YS have also been known to drop out of raid arrays, this can be fixed with a firmware upgrade from WDC, but this update doesn't fix the reading problem mentioned above. In our tests the WD5000YS the performs only about a third of the reading speed of WD4000YR using 9550SX-8LP, 64K stripe. The "newly" released WD5000ABYS also drops constaintly out of the Raid array so we haven't even been able to test it's reading speed yet, three drives dropped out after only two minutes of testing. Unfortunently we now also have 5 of these and starting to get fed up with Western Digital. So now I'm hoping for some comments from you all, have anyone used WD5000ABYS in raid 5? The only 500 Gb from WDC that seems to perform good in Raid 5 is the WD5000AAKS, however I haven't been able to confirm this myself. Can anyone here confirm this?

    WD5000YS, WD5000KS have had performance problems with reading information (as discussed in http://forums.storagereview.net/index.php?showtopic=25614 ) They perform well in Raid 0,1 though, and as a normal drive.
